CVE-2025-66624

CVE-2025-66624 affects the BACnet Protocol Stack prior to 1.5.0.rc2. The npdu_is_expected_reply function indexes APDU bytes (request_pdu[offset+2/3/5] and reply_pdu[offset+1/2/4]) without validating existence, allowing out-of-bounds reads in tiny PDUs. This can cause an immediate crash (DoS) on A...
